The `SubstitutionMap::new_inner()` method provides a more robust way to
create nested substitution maps, ensuring that only global substitutions
are inherited. This prevents potential issues with overlapping local and
upvalue addresses in nested scopes, such as during lambda inlining.
This change also includes:
- A new `try_fold_record` method in `folder.rs` to optimize record
literals into constant values.
- Updates to `inliner.rs` to recognize `Value::Record` for inlining.
- Various test cases to verify record optimization and constant folding.
Removes unused `flatten_tuple` function from optimizer utilities. The
functionality was moved to the `Folder` struct, making it more
contextually appropriate. This change streamlines the utility module and
improves code organization.
Extract common AST manipulation and folding logic into a new Folder
struct. This improves code organization and reusability. The Optimizer
now delegates these tasks to the Folder.
This commit reorganizes the optimizer code by creating a new `optimizer`
module. The `Optimizer` struct and its related logic remain in
`optimizer/optimizer.rs`, while `SubstitutionMap` and `UsageInfo` are
moved to `optimizer/substitution_map.rs`.
This change improves code organization and makes it easier to manage the
optimizer's components.
